How Stamp Duty Works in the Northern Territory

The NT uses a unique formula-based approach to calculate stamp duty, administered by the Territory Revenue Office. For most residential properties, duty is calculated using the formula D = 0.06571441 × V² + 15 × V where V = property value ÷ 1,000. For properties over $525,000, a flat rate of 4.95% applies.

Example Calculations

$400,000: V=400; D = 0.06571441 × 160,000 + 15 × 400 = $10,514 + $6,000 = ~$16,514
$525,000: approximately $23,928 (formula-based)
$600,000: 4.95% flat = $29,700
$800,000: 4.95% flat = $39,600
